GEORGE W. LANCASTER, OF RICHMOND, VIRGINIA, .ASSIGNOR TO UNIVERSALSCREEN & BLIND COMPANY, INCORPORATED, A CHARTERED COMPANY OF VIRGINIA.

SHUTTER-OPERATING MECHANISM.

ostess.

To all whom it may concern:

Be it known that I, GEORGE W. LArvoAsran, a citizen of the UnitedStates, residing at Richmond, in the county of Henrico and State ofVirginia, have invented certain new and useful Improvements in ShutterOperating Mechanism, of which the following is a specification.

My invention relates to shutter operating mechanism or more specificallyto mechanism for opening and closing shutters.

One object of the invention is to provide means for this purposeoperable by means of a horizontally disposed lever, or handle.

Another object of the invention is to provide means whereby the shuttermay be fastoned in various adjusted positions so that the extent of thewindow space closed may be regi'llated. D I

Still another object of the invention is to provide means in connectionwith the means operated by the lever, to effect sa d fastening of theshutter in adjusted posltlons.

A further object of the invention is to provide means whereby theoperating handle or lever employed may be shifted when not in use so asnot to interfere with the proper working of the adjacent window sash,

Still other objects of the invention are to provide such means of asimple nature so that the parts can be manufactured at small cost, andto provide the parts of such construction that they will prove durableand efficient in use.

Other objects will appear hereinafter from the description followingtaken in connection with the accompanying drawings.

The preferred embodiment of the invention is described and illustratedin said drawings, wherein,

Figure l is a fragmentary horizontal sectional view taken through awindow-frame and shutter showing the device of the pres-' ent inventionin connection therewith; Fig. 2 is an elevation showing fragmentarily,parts of a shutter, window-frame and any improved device, taken from theexterior: Fig. 3 is a plan view of the device attached from awindow-frame and. shutter; Fig. 4t is an elevation of the improveddevice; Fig. 5 is a vertical sectional view through the parts of Fig.4L; Fig. 6 is a cross sectional view on the line 6-6 of Fig. t; Fig. 7is a cross sectional view on the line 7 7 of Fig. 5; Fi g. S is an edgeview of the shifting link or Specification of Letters latent.

arm, and the parts connecting the same to the shutter; and Fig. 9 is aperspective view of the channel or controlling member.

teferring specifically to the drawings, 1 designates a window frame, orother stationary member and 2 designates a shutter or other hingedmember adapted to be swung relatively to the member 1. To the windowframe, as to the sill thereof, is fastened a bearing member 3 by meansof screws or the equivalent at 4:. In this hearing member is journaled apost or turnable shaft 5, to the lower end of which is rigidly fastenedas by means of a set screw 6, a shifting link or arm 7. Adjacent theouter end of the shifting link or arm is fastened a guide stud devicecoi'lsisting of a shank 8 having thereon a head 9 off set from the link.

The shutter has fastened thereto, as by means of screws 10, specificallyat the lower end thereof, a channeled or grooved guide or control member11, into the groove of which head=9 slidably extends, being positivelycoupled thereto by means of the flanges 12 of said control member. shaft5 is provided with an elongated. slot 13 in which is located a suitablelock member or pin 1 f. Said shaft also provided with a central,longitudinal here or recess in which is mounted the shifting mechanismfor the lock pin member. This lock pin or member projects beyond theshaft and is adapted to engage either of a plurality of notches such as15 provided at the upper edge of the bearing member 3. The pin isspecifically carried by a head 16 of a slidable, shifting stem or member17. To suitable serew threads provided in the bore is screwed a plug 18through which the stem 17 slidably extends. Beyond the said plug a knobor grip member 19 is preferably attached as by means of screw threads at20. Surrounding the stem 17 in the bore intermediate the head 16 andplug 18 is mounted a coil. or compression spring 20 which normallyforces the pin ll toward the notches.

An operating handle or lever 21 is slidably mounted vertically on acircumferential or rounded portion of the shaft or post 5 and is coupledthereto to turn there with as a unit by the engagement of a projectionor rib 23 on the post engaging slidably in a slot 2% of the handle orlever. it will be noted that the rounded portion 22 The i of the shaft 5is provided by reducing the shaft or post at its upper end, whichreduction forms an annular shoulder such as shown, and upon which thelever 21 normally rests. Through the vertical movement of the handle, itcan be raised on the post to disengage the projection 23, whereby thehandle or lever may be turned independently of the post for the purposelater to be set forth.

In use the operating handle is normally in position where the projection23 and slot 2% are in engagement. While in such posi tion, in order toopen the shutter, the knob 19 is pulled Vertically which efieetsshifting of the pin 1t and raises the same from engagement with thenotches 15, whereupon the handle is turned and by the engagement of head9 on link 5 with control member 11, the shutter is opened to the desiredextent. When the shutter has been fully opened or opened to the desiredextent, knob 19 is released and thereupon spring 20 forces the pinliinto the adjacent notch of the plurality of notches at 15. In use ithas been found that the desirable size of the operating handle or leveris sometimes too long to permit the adjacent window sash to close afteropening of the shutters. In order to render the handle capable ofmovement to the position where it will not interfere with the closing ofthe shutter, the parts have been so constructed that the handle may beraised to disengage the pin 14 and notches 15. After such disengagement,the handle can be t'reelyturned to any desired position for location. Inorder to close the shutters, the knob 19 is of course raised todisengage pin 1% and notches 15, so that the operating handle can bethereafter swung or shifted to effect closing. After effecting closing,the shutter is locked in such position by the engagement of the pin 1%and proper notch 15.

Changes such as may be made within the spirit and scope of the appendedclaims are reserved.

Having thus described my said invention, what I claim is 1. Incombination with a member to be swung, a turnable member, a shifting armon said turnable member for said first mem' her, a handle on saidturnable member, a lock member separate from said handle mountedslidable independently of the handle on said turnable member, and asecond lock member engaged by said lock member.

In combination with a member to be swung, a turnable member, a bearingmember for said turnable member pr vided with a plurality of notches, ashifting arm on said. turnable member for said first member, handle onsaid turnable member, and a lock member slidably mounted on saidturnable member engageable with said notches.

3. In combination with a member to be swung, a turnable member, ashifting arm on said turnable member for said first memher, a lockmember, said turnable member provided with an elongated slot through andbeyond which said lock member extends, a second look member engaged bysaid lock member, and a stem carry'ng said first lock member slidablymounted on said turnable member.

i. In combination with a member to be swung, a turnable member, abearing for said turnable member provided with a plurality of notches, ashifting arm on said turnable member for said hrst member, aspring-pressed locking device mounted on said turnable member having alock member engageable with said notches, said turnable member providedwith an elongated slot through and beyond which said lock memberextends, and an adjustable handle mounted on said turnable member.

In combination wi h a member to be swung, a control member fastenedthereto, a turnable member, a shifting arm on said turnable member inoperative relation with said control member, a bearing member for saidturnable member provided with a plurality of notches, a slidable stem insaid turnable member having a lock member thereon engageablewith saidnotches, a spring surrounding said stem, a plug member in said turnablemember engaging said spring, an adjusting member for said stem exteriorof said turnable member, and a handle mounted on said turnable member.

In testimony whereof I have aflixed my signature in presence of twowitnesses.
